2 Claims.

The present invention relates to improvements in firearm structures andrelates more particularly to means for absorbing recoil shocks betweenthe receiver and the complemental stock 1. of a given firearm.

One of the objects of the present invention is to provide a firearmstructure having a superior construction and arrangement of partswhereby the connection of a receiver and a stock is of such character asto minimize or eliminate the splitting of the stock occasioned by recoilshocks or stresses incident to the discharge of the firearm.

Another object of the present invention is to provide a superior firearmconstruction wherein means is provided adjacent the receiver-cavity in astock for holding the walls of such cavity or recess from spreadingunder recoil stresses and without requiring the use of transverse screwsor the like.

With the above and other objects in view, as will appear to thoseskilled in the art from the present disclosure, this invention includesall features in the said disclosure which are novel over the prior artand which are not claimed in any separate application.

In the accompanying drawings, in which certain modes of carrying out thepresent invention are shown for illustrative purposes:

Fig. 1 is a view of the central portion of a firearm structure embodyingthe present invention and shown partly in side elevation and partly invertical central-longitudinal section;

Fig. 2 is a horizontal sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is a transverse sectional view taken on the line 33 of 1;

Fig. 4 is a broken view in vertical central-longitudinal section of thecentral portion of the stock;

M Fig. 5 is a top or plan view thereof;

Fig; 6 is a view in side elevation of the triggerplate member detached;

Fig. 7 is a top or .plan View thereof; and

Fig. 8 is a broken underside view of the re ceiver-member detached.together with a portion of the barrel.

The particular firearm herein chosen for purposes of illustrating oneform which the present invention may assume. comprises in the main astock Ill, a receiver-unit H and a barrel l2. The stock H3 is pre erablymade of wood or other suitable heat-insulating material and thereceiver-unit H, in the instance shown, comprises a receiver-member l3and a trigger-plate memher l4. Both of the members I3 and I4, as well asthe barrel l2, are preferably formed of highgrade steel.

The two complemental members l3 and Id of the receiveror frame-unit llmay be secured together in any suitable manner such, for instance, as byproviding the receiver-member IS in the lower portion of its hollowinterior with a pair of longitudinally-extending coupling-ribs I5-l5laterally spaced apart and projecting respectively inwardly toward eachother from the respective opposite side-walls of the member it, as isespecially well shown in Fig. 3. Resting respectively upon the uppersurfaces of the coupling-ribs lli-l5 just referred to are couplingribsl$lfi projecting outwardly respectively in opposite directions from theopposite sides of a lug ll upstanding from the trigger-plate member l4about midway the length thereof.

The lower portion of the receiver-member l3 and the major portion of thetrigger-plate member I4 is normally accommodated in a verticallongitudinal recess l8 formed in the stock Ill before referred to, andintersecting both the upper and lower surfaces thereof.

It will be noted by reference to Fig. 5 in particular that the verticalrecess 18 in the stock It] is wider at its forward portion than it is atits rear. At the junction of the narrow and wide portions of the recessl8, each of the side-walls is formed with two forwardly-facingrecoil-seats l8l9 respectively located adjacent the respective oppositesides of the recess l8. Inwardly of each of the seats is, the materialof the stock is extended forwardly beyond the vertical plane of theadjacent recoil-seats 9 to provide a stabilizing-rib or lip 28, one ofwhich latter is located adjacent each of the recoil-seats Ill-l9, andwhich act in a manner as will hereinafter appear to stabilize therespective opposite sidewalls of the recess H3 in the stock U3.

The trigger-plate member l4 before referred to of the receiver-unit H,is relatively narrow transversely at its rear portion and relativelywide at its forward portion to fit the respective narrow and wideportions of the vertical recess H3 in the stock Ill. The saidtrigger-plate member is provided adjacent its rear end with a dependingguard-loop 2i housing the finger-piece of a trigger 22. The rear portionof the trigger plate member It also mounts a firing mechanism which,however, requires no detailed description herein other than possibly tonote that the said firing-mechanism includes a hammer .33, a sear 24 anda hammer-sprin 25.

The relatively-wide forward portion of the trigger-plate member M isprovided with a vertical magazine-receiving passage 26 adapted toreceive a box-magazine (not shown) in a manner well known in the firearmart. On each of its respective opposite sides and about midway of itslength, the trigger-plate member I4 is provided with one of twocorresponding stabilizing-ribs or lips 21. Eachof the stabilizing-ribs2'! just referred to, projects rearwardly and overlaps the outer face ofthe adjacent one of the stabilizingribs 20 of the stock I 0, as isespecially well shown in Fig. 2. Preferably, therear face of each of thestabilizing-ribs 21 of the trigger-plate mem ber l4 bears'against theadjacent one of the forwardly-facing recoil-seats 19 of the stock I0.xPreferably also, the forward face of each of the spects as illustrativeand not restrictive, and all changes coming within the meaning andequivalency range of the appended claims are intended to be embracedtherein.

I claim:

1. A firearm structure including in combination: a stock having aninterior vertical longitudinal recess therein which is relatively wideat its forward end-portion and relatively narrow at its rearend-portion, the said stock being formed in each of the oppositeside-walls of the said recess at the junction of its two saidend-portions with one of two vertical stabilizing-ribs each'having anoutwardly-facing surface; a receiver-member extending into the upperpart of the recess in the said stock; a trigger-plate member having arelatively-wideforward end-portion and a relativestabilizing-ri-bs ofthe stock lfl also engages a with the rear face of the adjacent widefront portion of the trigger-plate member, Hi to assistiin absorbingrecoil shocks,

The central lug ll of the trigger-plate member I is formed centrally ata point above the coupling-ribs |6'l6 thereof, with an abutment-rib 28having its forward face normally in engagement with the rear face of. anintegralweb 29' extending transversely across the hollow interior of thereceiver-member 13 adjacent the lower end and'aboutmidway the lengththereof.

The respective rear portions of the members I73 and I4, may, ifdesired,rbe coupled to the stock In in a suitable manner such, forinstance, as the manner shown in my co-pending application Serial No.473,11 filed January 21, 1943.

C When the firearm is discharged, the receivermember I3 will, of course,violently recoil under the shock and such recoil will be transmitted tothe trigger-plate member I4 by way of the web 29 of the receiver-memberf3 and the abutmentrib 28 of the trigger-plate member 14. The recoilshocks thus received by the trigger-plate f member 14 will, in turn, betransmitted by the rear faces of the stabilizing-ribs 2'i--2l and theadjacent portions of the trigger-plate member M, to' the stock In. I

When the recoil shocks are received by the stock Win the manner'asabove'described, there is a natural tendency for the relatively-thinsidewalls of the vertical recess I8 in the stock Ill, to

spread laterally outwardly and eventuallyjto weaken the stock and causethe splitting thereof, unless such tendency is ofiset. The outwardflexing of the side-walls of the recess I8 is prevented or so minimizedas to be substantially harmless,

by the engagement of the inner face of each of the stabilizing-ribs 21of the trigger-plate member M with the outer face of the adjacent one ofthe two stabilizing-ribs 2B of the stock Ill.

By means of the present invention, the tendency of the'stock to splitunder the shock of recoil strains its overcome or minimized withoutrequiring the use of special bindingor couplingscrews or thelike-passing laterally through the stock.

Thus, not only is the cost of such bindingscrews-obviated, but morespace is left free in thefirearm structure for the accommodation ofvarious features of the firearm mechanism, magazine, etc.

The invention may be carried out in other specific ways than thoseherein set forth without departing from the spirit and essentialcharacteristics of' the invention, and the present embodiments are,therefore, to be considered in allre-- ly-narrow rear end-portionrespectively extending into the lower parts of the respective forwardand rear end-portions of the recess in the said stock, the saidtrigger-plate member being formed on each of its respective oppositesides at the junction of its relatively-wide forward end-pore saidtrigger-plate member and'constructed' and arranged to transmit therearward recoil shock of the said receiver-member to the saidtriggerplate member.

.2. A firearm structure including in combination: a stock having aninterior vertical longi-' tudinal recess therein which is relativelywide at its forward end-portion and relatively narrow at its rearend-portion; the said stock being formed ineach of'the oppositeside-walls of its saidrecess at the junction of its two saidend-portions with one of two vertically-extending andforwardly-proje'cting stabilizing-ribs each having an outwardly-facingsurface; a receiver-member extending into the upper part of the recessin'the said stock; a'trigger-plate member having a relatively-wideforward end-portion and a relativelynarrow rear end-portion respectivelyextending into the lower parts of the respective forward and rearend-portions of the recess in the said stock,

the said trigger-plate member being formed on each of its'respectiveopposite sides at the junc-f tion of its relatively-wide forwardend-portionand its relatively-narrow rear'end-portion with one of twovertically-extending and rearwardly projecting stabilizing-ribs, eachof, the last-mentioned stabilizing-ribs having an inwardly-facingsurface engaging with the outwardly-facing surface of the adjacent oneof the said vertical and forwardly-projecting stabilizing-ribs of thesaid stock to thereby hold the side-wallsof the recess in the said stockagainst undue outward fiexure; and coupling-means coupling the saidreceiver-' member to the said trigger-plate member and constructed andarranged to transmit the rear' ward recoil shock of the saidreceiver-member to the said trigger-plate member,
